y SLIDING-SHAKLE LOCK.

Application eld September 10, 1924. Serial No. 736,924.

ing stolen or, in other words, to locks of the general sliding or adjustable shackle type shown in the patent to Benson, No. 1,223,928, granted April 24, 1917, in which the lockcasing or block has openings extending from top to bottom or front to rear completely through the casing or block to adjustably receive the parallel arms of the substantially I U-sliape shackle, which arms may extend beyond each end ot' the casing and are adapted to be engaged by the lock mechanism extending in said openings or passageways in the path of travel of said arms respectively.

The invention resides more particularly in the locking mechanism and in the combination and interrelation thereof with thel casing .and'sliackle, and also in details of the: casing or block and in details of the shackle construction.

The primar objects in view are to provide a very kcheap reliable positive locking means; to provide a construction wherein the locking element or mechanism may be slipped on the arms of the shackle and the latter together with said locking mechanism correctly positioned in one plate of the casing or block and the other plate of the casf ing then applied and the whole riveted together, holding all parts permanently in corp-pV rect position and relation, thus greatly rer i ducing the labor and time heretofore rev quired in assembling such locksgto provide f such a combination ot the shackle and locking element that the former, if-inserted from the correct end or direction, will be positively engaged by the locking element and positively held thereby until released by the movement ol said locking means or element by the key to inoperative.position, but, if in serted from the wrongend oi' direction will l be yieldingly engaged by said locking ele-v nient, but will not be positively held by said locking element, and may be pulled easily out of the casing or block without any need to use the key, whereby all need for guard stop means ior preventing insertion `from the wrong end oi the casing or wrong direction is eliminated; to provide a spring lock mechanism which maybe held by the key in inoperative position when the key has been turned to a definite position and will not act to turn the key from suoli definite position when the key is releasedl by the operator; and to provide a shackle having its loop or closed end provided with opposed faces extending from the ends of the paralrl lel arms and converging toward each other with straight walls at an angle of approximately sixty degrees to obtain the quickest centering angle and the closest possible adlJustmentto hasp or fastener over a rela- .tively large range so as to prevent rattling and, of more importance, to make such a tight tit that the movable lug I can not be twisted, turned or rocked to such a position as to permit the removal of the spare tire even though the bolt J be removed, and so that the body or casing of the lock will' so Vtightly engage the lug I as to prevent the insertion between the arms M of said shackle and the body or casing of said Alock and the lu I of a prying instrument, all of which ob]ects, among others,fare accomplished by the combination, construction and arrangement of parts all as hereinafter more particularly set forth, described and claimed.

In. the accompanying drawing, inwhich onlytwo embodiments of my invention are shown merely by way of illustration of in-.

stances of the practice of my invention to .aid in its better understanding, but `with no intention of being limited to the details thereof, it being recognized that itis capable ot numerous other embodiments: y n

Also, itis to be noted that, while the key-hole disc or washer `E is desirable, it is not essential.

`To assemble, the spring element Will be -slipped along the arms M from their free hole disc or Washer E fitted in place, thev plate B fitted in place, and then the ends,I

of the rivets C will be spread and the assembly operation will .be complete.

From the above description taken with the illustration of the drawing it will be obvious that the shackle may easily be improperly inserted from the bottom, but it is also very obvious that if said shackle should be inserted from the bottom or rear there would be no abrupt faces of thenotches 7 that could. be engaged by the lower or rear edges of the sides 2 to prevent endwise. withdrawal of said arms.

Also, from Fig. 3, it will be seen that when the arms M have been properly inserted from the top or front and are locked by the sides 2 of the spring element, they maybe released by the insertion and operation of the key L, which is adapted to en-q gage the lower oi' rear portions of lsaid sides 2 and spread them apart so that they will lie out of the paths of said notches, and if said key L'be turned to, and left at, a position at right angles to its insertion position it will serve as a block holding said sides 2 spread to inoperativeposition, permitting the easy and quick unimpeded removal and insertion of the shackle with one hand.

In the modification illustrated in Figures 9 and l0, iii place of the single spring elenient, two springs 2, each conforming in size, inclination, shape and arrangement to said sides 2, are substituted, being preferably held in place to the respective plates A and B by rivets 2b preferably integral with the respective plates. Otherwise Ythe construction, operation and conihination of parts are in all respects the same as that ofthe en'ibodiment illustrated in Figures l to 8.

The letter F designates the skeleton rim forming part of, and supported by, the usual iron tire rack, not shown, with which most autoniobiles are provided for carrying spare tires. A demountable rim G adapted to have mounted on it a pneinnatic tire or spare easing, is loosely fitted over the rim F. A metal lug H, welded, riveted, or both, to the rim F, is provided With a notch or recess in its upper end, a perforation ,interme-r diate its ends, and a bolt hole near its lower end, and an opposing removable lug I, ofv

usual type, Ahaving its lower portion downwardly inclined away fromlug H and; provided with a perforation and bolt hole registering with the'perforation and bolt hole in lug I'I and having a registering notch or recess in its upper end, is normally tensionally held by a bolt J and its nut with its ad jacent face of its inclined portion in engagementwith thedeinountable rim G, forcing the latter over on rim F and also spreading the rim G radially, to secure the 'rims F and G together and prevent any substantial rela-V tive movement between these rims.

To surely lock the removable lug I to the lug I-I to prevent rattle and to prevent the unauthorized removal of the rim G with the spare tire mounted thereon, itv is essential to provide a lock that can be so 'adjusted that the lock block or body will lie so closely to the adjacent face of the lug I as to prevent the insertion of a prying instrument between said lug I and the lock block or body to pry it off, and which will lie so closely to said lug I and will bind said lug I and lug H so tightly as to prevent the lug I- from being twisted or rocked in any direction relative to lug H to such degree as would, even should the bolt J be removed, permit the `spare rim Gto be removed With its spare tire, and it is to accomplish this end that the shackle is provided with the converging faces- 8 inclined at anv angle of approximately GO degrees, as illustrated in Fig. l.

In use the shackle will be applied to the lugs H and I with the arms M extending in the registering recesses and the registering perforations thereof and with the free ends of said arms presented rearwardly; the lock block or casing isthen applied'to the free ends of said arms and forced along the same until it is in tight engagement With the adjacent face of lug I with the opposing faces of lugs I-I and I parallel, to, and in full engagement with, each other, and the opposed faces `of inclined portions 8 in biting engage` ment with the wallsof the recess and perforation respectively in lug H, thus guarding against any play between the lock and saidlugs thus preventing any rattling or noise, i and guarding against any forced movement of the lug` I, in any direction with relation to lugl Il, of sufficient extent as to render said lug I inoperative to hold the rim G on rim Feven though the usual bolt J be removed in an attempt at unauthorized removal of the spare tire and rim.V
